I figured if you looked at the over all relationship you would see if there was a pattern that was cause for leaving him or accepting how he is and working it out.
Hope it all works out for you.
I think your boyfriend need to understand that you need him in any situation.but I think you should give him a chance.if he still don't get it, saty away from him because that shows that he will not be there for u,if you were the one at the hospital
